Guide to the Interpretation of Space Group Symbols
Author: Stanley K Dickinson (Jr)
Publisher:
ISBN:
Category :
Languages : en
Pages : 37
Book Description
A scheme for presenting and interpreting the 230 space groups is developed. The scheme is based on the addition of symmetry operations to translation operations in conformance with the symmetry requirements of the seven crystal systems. The stepwise development from crystal systems to space groups is traced in the report and centerfold chart. Complete notes on deciphering the space group symbols and for correlating the Schoenflies and the International systems of abbreviations are included. (Author).

Effects of Experimental Parameters on Thermoluminescence of a Type II-a Diamond
Author: Albert D. Johnson
Publisher:
ISBN:
Category : Crystals
Languages : en
Pages : 42
Book Description
Thermoluminescence provides a method for studying properties of those crystalline imperfections which behave as electron traps and recombination centers in wide bandgap materials. This approach, however, has been used relatively little, possibly due to the fact that the shapes and intensities of thermoluminescent glow curves are functions of several experimental parameters and are often complicated by the overlapping of a number of individual glow peaks. In the present work, experimental parameters were isolated and some of their effects on thermoluminescent glow curves were analyzed. This yielded information on activation energies associated with trapping levels, the nature of the kinetics involved in electron transitions, and electron retrapping. A Type II-a diamond, which has a wide distribution of thermoluminescent glow peaks, was used in this work. (Author).

On the Theory of Boolean Formulas
Author: E. W. Samson
Publisher:
ISBN:
Category : Algebra, Boolean
Languages : en
Pages : 38
Book Description
The theory of substitutions for Boolean formulas developed in a previous report is applied here to the determination of those s-tuples of formulas that may be allowable replacements for s -tuples of sub-formulas of given Boolean formulas. The criteria of allowability are very general and flexible, yet may be expressed with great precision and ease. The results formalize and extend various known isolated instances. They may be used for the study of a large number of problems in the theory and application of Boolean formulas and functions.

State - Logic Relations in an Iterative Structure for Autonomous Sequential Machine
Author: William F. King (III)
Publisher:
ISBN:
Category : Cellular automata
Languages : en
Pages : 30
Book Description
The state-logic relations are determined in an iterative structure for any autonomous sequential machine. A model (unlike that of Mealy) is used in which delay is distributed throughout the machine. Theorems are presented which prescribe the interconnection of identical elements to realize any autonomous sequential behavior. Synthesis, as described here, yields a more costly machine in terms of delay elements than those of previous workers. In addition to the iterative structure, increased speed of operation is the advantage bought by the extra delay elements.
